Should we have a CR committee? Does a CR committee have sufficient ROI?
This idea is connected to the discussion that the Architecture Committee is having on groups / (sub)teams working on special areas.
A potential Code Review committee / working group could exist for a limited time. (It would be different from a Collaboration working group, see T119030.)
This group would cover social, technical, and organizational aspects of Code Review and work on improving Wikimedia's Code Review process in T78768.
There was a session about the topic of code review (T149639: Better code review processes for reviewers) at the 2017 Wikimedia Developer Summit.
During that session, consensus was reached to form a code review working group. See action items on the summary page for that session.
